expand ((-2-x)^2)/4

expand

\frac{( - 2 - x ) ^{2}}{4}

\frac{x ^{2}}{4} + x + 1

Solution steps

\frac{( - 2 - x ) ^{2}}{4}

(- 2 - x)^{2} = 4 + 4 x + x^{2}

= \frac{4 + 4 x + x ^{2}}{4}

Apply the fraction rule:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{4 + 4 x + x ^{2}}{4} = \frac{4}{4} + \frac{4 x}{4} + \frac{x ^{2}}{4}

= \frac{4}{4} + \frac{4 x}{4} + \frac{x ^{2}}{4}

Apply rule

\frac{a}{a} = 1

\frac{4}{4} = 1

= 1 + \frac{4 x}{4} + \frac{x ^{2}}{4}

Divide the numbers:

\frac{4}{4} = 1

= 1 + x + \frac{x ^{2}}{4}

Rewrite in standard form

= \frac{x ^{2}}{4} + x + 1

\frac{2 ( 4 - π )}{4}

a (2, - 1, 3)

e^{2 x} (e^{2 x} + x^{2} e^{2 x})

\frac{2 ( 2 e - 1 )}{3 e}

\frac{- 2 a ^{2} - 2 ab - b + 2}{( a - 1 ) ( - 4 - 2 a )}
